CHICAGO--(BUSINESS WIRE)--OAG, the air travel intelligence
company, has released the industry’s first On-time
Performance (OTP) Star Ratings, setting the standard for the world’s
best airlines and airports in OTP. The newly released data highlights
exceptional OTP from Delta Air Lines, the only legacy carrier to meet
the criteria for earning 3 stars, and continued excellent performance
from Hawaiian Airlines, the only North American airline to earn 4 stars.

This new biannual rating system is a global accreditation program that
recognizes exceptional OTP across all airports and airlines regardless
of size, geographic location or aviation peer group. The awards showcase
only the best performers – just 11 airports and three airlines globally
earned a 5-star rating, which requires an OTP of at least 90 percent.

Delta’s performance is particularly noteworthy, as a 3-star rating for a
legacy carrier is difficult to achieve. In a U.S. air travel ecosystem
that relies on major hubs, it’s easy for a single delay or cancellation
to knock an entire day of flights off schedule. Despite managing one of
the largest fleets in the world, Delta has remained a cut above its
competitors. American and United both finished solidly, earning 1-star
ratings with an OTP of 78.7 and 78.6 percent, respectively.

Some of North America’s largest airport hubs managed to earn 3 stars
with very good OTP despite operating some of the most heavily used
airports in the world. Atlanta’s Hartsfield-Jackson International
Airport (84.5 percent), Charlotte Douglas International Airport (83.1
percent) and Minneapolis St. Paul International Airport (84.3 percent)
all performed strongly for airports of their size. Hilo International
Airport was the only US airport to achieve 5-star on-time performance,
while Lihue Airport came out with an 89.4 percent OTP and was the only
North American airport to earn a 4-star rating.

“As the world’s skies and airports become more crowded and congested,
punctuality has become one of the criteria by which the outstanding are
set apart from the ordinary,” said John Grant, Senior Analyst, OAG.
“Today’s travelers use OTP as a key performance indicator to judge the
quality of an airline or airport, making it critical for travel
providers to continually look for new ways to optimize and improve their
punctuality.”

While OAG’s
Punctuality League celebrates annual performance against airline and
airport peers, the OTP star rating is designed to benchmark against set
criteria, defined by industry and flight status information experts. OTP
is measured across the whole year – and awarded twice a year in April
and October – through a definitive benchmark, using set criteria as
defined by OAG, the flight status experts.

To achieve an OTP star rating, the world’s airlines and airports must

of 600 operations a month and OAG must receive flight status information
for no less than 80 percent of scheduled flights within a 12-month
period.
